DESIGN OF SLABS-ON-GROUND 360R-5
complete the design. 
Chapter 12 
presents special require-
ments for slabs in refrigerated facilities. 
Chapter 13 
covers
the design methods used to reduce the effect of drying,
shrinkage, and curling. References are listed in 
Chapter 14
.
Design examples in the 
Appendixes 
illustrate the application
of selected design methods.
1.6—Further research
There are many areas where additional research is needed.
Some of these areas are:
• Developing concrete mixture proportions that have low
shrinkage characteristics but are still workable, finishable,
and provide a serviceable surface;
• Flexural stress in slabs with curl and applied loads and
how curling stresses change over time due to creep;
• Soil properties and how they may change over time
under load repetitions, long-term loading, or both;
• Establishing an allowable differential deflection
between the tops of the slab on each side of the joint
and spacing between slab joint edges to minimize spalling
due to lift truck traffic; and
• Recommended joint spacing using FRC.
CHAPTER 2—SLAB TYPES
2.1—Introduction
This chapter identifies and briefly discusses the common
types of slab-on-ground construction. The term “slab-on-
ground” is the preferred nomenclature although, in practice,
the term “slab-on-grade” is often used to mean the same thing.
Slab-on-ground is a general term that includes interior slabs
subject to loadings as described in 
Chapter 4
. These include
industrial, commercial, residential, and related applications.
Although the term might also include parking lot and roadway
pavements, these are not specifically addressed in this guide.
